Mathematics

The expression that represents the approximate length of BC is; A: (3) sin(66)/sin (38)

<h3>Trigonometric Ratios</h3>

From the given triangle ABC, we see that;

∠A = 66°

∠C = 38°

AB = 3

Thus using sine rule, we have;

AB/sin C = BC/sin A

3/sin 38 = BC/sin 66

BC = (3sin 66)/sin 38

BC = 4.45

Answer:

d) 35ft

e) 6 seconds

f) 250°

Step-by-step explanation:

If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.

   36 secs = 360°

⇒ 1 sec = 360/36 = 10°

d)  After 9 seconds, it has turned:

9 x 10 = 90°

Therefore, it will be 15 + 20 = 35ft from the wall

e) 60° = 6 seconds

f) 25 seconds = 25 x 10 = 250°
